Second Lieutenant is the entry-level commissioned officer rank in the United States Marine Corps. A Second Lieutenant generally commands a platoon consisting of 16 to 44 Marines, including two or more squads lead by a senior non-commissioned officer. Second Lieutenants are often unofficially referred to as "butterbars" or "nuggets", in reference to their golden bar insignia.

Because of their relative inexperience in command, Second Lieutenants often receive assistance and mentoring from more experienced commissioned officers and the senior non-commissioned officers who serve with them. On-the-job training helps prepare Second Lieutenants for future promotions and command responsibility over larger units of Marines.

Marines who have completed an ROTC program or a four-year college degree combined with Officer Candidate School may enter the Marine Corps with a commission as Second Lieutenant. In times of war, exemplary enlisted soldiers may also receive a "battlefield commission" to Second Lieutenant to reward leadership and bravery on the field, although this is rare in modern times.

Second Lieutenant is the 18th rank in the United States Marine Corps , ranking above Chief Warrant Officer 5 and directly below First Lieutenant. A second lieutenant is a Commissioned Officer at DoD paygrade O-1, with a starting monthly pay of $3,826.
